It's been done for Batman and Superman so now it's the Doctor's turn. Psychologists at the University of Aberdeen Face Lab have revealed a composite face of all the actors who have played the Time Lord. See the image after the jump.

David Robertson of the Face Lab told the BBC:

It's interesting that the face we have developed is not dominated by
the features of any one of the actors to have played The Doctor.

Rather it represents a combination of the averaged features of each actor to have taken on the role.

Indeed, this face average could guide future casting directors in their search for the ideal actor to play the Time Lord.
